In the last two years, I've found that about 1 in 4 of my purchases from China will never arrive. Obtaining refunds is an easy process but frustrating. Many of the sellers will have rankings that make them seem trustworthy only to disappear completely. And we can also lay blame on the western hemisphere. Canada and USA postal systems bear the brunt of the costs of "free" delivery. They will give these packages low priority. Packages will languish for months and when items finally arrive, it can be difficult to arrange payment with the seller after a refund.
